Number comprehension by a grey parrot (Psittacus erithacus), including a zero-like concept

A Grey parrot (Psittacus erithacus) that was able to quantify 6 item sets (including subsets of heterogeneous groups, e.g., blue blocks within groupings of blue and green blocks and balls) using English labels (I. M. Pepperberg, 1994a) was tested on comprehension of these labels, which is crucial for numerical competence (K. C. Fuson, 1988; see also record 1987-98811-000). He was, without training, asked "What color/object [number]?" for collections of various simultaneously presented quantities (e.g., subsets of 4, 5, and 6 blocks of 3 different colors; subsets of 2, 4, and 6 keys, corks, and sticks). Accuracy was greater than 80% and was unaffected by array quantity, mass, or contour. His results demonstrated numerical comprehension competence comparable to that of chimpanzees and very young children. He also demonstrated knowledge of absence of quantity, using "none" to designate zero.     

Thought-action fusion and its relationship to schizotypy and OCD symptoms

Thought-action fusion (TAF) is a cognitive bias that has been linked to obsessive-compulsive disorder (OCD). Preliminary evidence suggests schizotypal traits may be associated with some types of OCD obsessions but not others. We examined the relationship between each of the two major types of TAF (i.e., likelihood and moral), schizotypal traits, and OCD symptoms in 969 nonclinical undergraduate students. We hypothesized that likelihood TAF would be associated with schizotypal traits; whereas moral TAF would not. Consistent with prediction, schizotypal-magical thinking was significantly associated with likelihood TAF even after controlling for the effects of OCD symptoms, general anxiety, and depression. Moreover, the relationship between likelihood TAF and OCD symptoms was significantly attenuated after controlling for schizotypal traits. In contrast, moral TAF demonstrated negligible association with OCD symptoms, depression, or schizotypal traits. These findings provide preliminary support for the linkage between likelihood TAF and schizotypal traits.     

Effects of an Internet-based voucher reinforcement program for smoking abstinence: a feasibility study

The present study tested the feasibility of an Internet-based method to obtain objective evidence of smoking abstinence and to deliver vouchers for evidence of abstinence. Four heavy smokers participated in this 4-week study. Twice daily, participants made video recordings of themselves providing a breath carbon monoxide (CO) sample with a Web camera. The video was sent electronically to the smoking clinic. Participants could earn vouchers for gradual reductions in breath CO during an initial shaping condition, and then for achieving abstinence (CO < or = 4 ppm). Vouchers could be exchanged for merchandise at select Internet vendors. Relative to baseline conditions, participants substantially reduced their smoke intake, and 3 achieved sustained periods of abstinence. The study suggests that an Internet-based voucher reinforcement program is a feasible method to promote abstinence from cigarette smoking.

Muscularity Beliefs of Female College Student-Athletes

Female athletes in the United States face the paradoxical challenge of acquiring a degree of muscularity to be successful in their sport, yet they also endure pressure from societal expectations of femininity that often don??t conform with the notion of muscularity. To address research questions about how female student-athletes balance muscularity and femininity, we conducted a mixed-methods study to examine muscularity beliefs among female student-athletes, female college students, and male college student-athletes. We quantitatively examined Drive for Muscularity Scale (DMS) scores from 221 participants attending college in the Midwestern US. Results indicated that female student-athletes reported significantly higher DMS scores than female students, but male student-athletes reported the highest DMS scores in the sample. Qualitative results indicated that female student-athletes wanted to be muscular for these reasons: functionality (45%), health (42%), external gratification (21%), and internal gratification (18%). Only 16% of female student-athletes did not want to be muscular, whereas every male student-athlete reported a desire to be muscular. The results of this study can be used to better understand the unique drive for muscularity among athletes, particularly female college student-athletes who live the paradox of negotiating societal standards of femininity with this desire to be muscular. This enhanced understanding can help create more nuanced interventions for coaches, administrators, and mental health professionals to use to help female student-athletes create space to resist constraining societal gender ideologies. Doing so can help these student-athletes actualize their athletic potential on the field as well as their interpersonal and intrapersonal potential off the field.     

Positional effects in the lexical retuning of speech perception

Listeners use lexical knowledge to adjust to speakers’ idiosyncratic pronunciations. Dutch listeners learn to interpret an ambiguous sound between /s/ and /f/ as /f/ if they hear it word-finally in Dutch words normally ending in /f/, but as /s/ if they hear it in normally /s/-final words. Here, we examined two positional effects in lexically guided retuning. In Experiment 1, ambiguous sounds during exposure always appeared in word-initial position (replacing the first sounds of /f/- or /s/-initial words). No retuning was found. In Experiment 2, the same ambiguous sounds always appeared word-finally during exposure. Here, retuning was found. Lexically guided perceptual learning thus appears to emerge reliably only when lexical knowledge is available as the to-be-tuned segment is initially being processed. Under these conditions, however, lexically guided retuning was position independent: It generalized across syllabic positions. Lexical retuning can thus benefit future recognition of particular sounds wherever they appear in words.     

Expanding the single-case study: a proposed psychoanalytic research program

This paper offers a proposed program of research using single-case time-series methods that can be used by practicing clinicians. The paper is written for psychodynamically oriented clinicians who want to get involved in psychotherapy research and make contributions to the scientific literature. How to measure treatment outcomes and psychodynamic constructs are discussed. With few exceptions, conducting single-case time-series research using psychodynamic psychotherapy has far more advantages than disadvantages.     

How Abusive Supervision Affects Workplace Deviance: A Moderated-Mediation Examination of Aggressiveness and Work-Related Negative Affect

Purpose

This research examines the linking mechanisms and conditional processes underlying the abusive supervision and workplace deviance relationship. Based primarily on Affective Events Theory, it was hypothesized that work-related negative affect would mediate the relationship between abusive supervision and workplace deviance, and that this indirect effect would be moderated by employee-based and organization-based aggressiveness.

Design/Methodology/Approach

Two independent studies were conducted, including diverse working samples and multi-wave data, to test these relationships through mediation and moderated-mediation bootstrapping procedures.

Findings

Both studies suggest that work-related negative affect mediates the abusive supervision and workplace deviance relationship. Mixed findings were found for the moderating effect of employee-based and organization-based aggressiveness. In Study 1 higher levels of employee-based aggressive beliefs and attitudes increased the magnitude of the indirect effect; however, in Study 2 when taking into account organization-based aggressive norms only the facet of social discounting bias increased this relationship. In Study 2 higher levels of organization-based aggressive norms also increased the magnitude of the indirect effect for supervisor-directed deviance.

Implications

Theoretical and practical implications of these findings suggest a movement toward an emotion-centered process-based theory of workplace deviance.

Originality/Value

A central question in organizational behavior research revolves around what drives employees to engage in various workplace behaviors. Replicating research that suggests abusive supervision is an important factor in this question, this research helps illuminate the processes underlying this perception-to-behavior link, as well as the boundary conditions of these processes.

     

Action embellishment: an intention bias in the perception of success

Na?ve theories of behavior hold that actions are caused by an agent's intentions, and the subsequent success of an action is measured by the satisfaction of those intentions. However, when an action is not as successful as intended, the expected causal link between intention and action may distort perception of the action itself. Four studies found evidence of an intention bias in perceptions of action. Actors perceived actions to be more successful when given a prior choice (e.g., choose between 2 words to type) and also when they felt greater motivation for the action (e.g., hitting pictures of disliked people). When the intent was to fail (e.g., singing poorly), choice led to worse estimates of performance. A final experiment suggested that intention bias works independent from self-enhancement motives. In observing another actor hit pictures of Hillary Clinton and Barack Obama, shots were distorted to match the actor's intentions, even when it opposed personal wishes. Together these studies indicate that judgments of action may be automatically distorted and that these inferences arise from the expected consistency between intention and action in agency.
